How to Replace a Side Mirror Signal Light Bulb in a S430 Mercedes Benz

by Daniel Valladares

Unlike most vehicles that use bulbs for their signal lights, the Mercedes Benz S430 uses an LED light strip for the lights in its side mirrors. Although you won't have to purchase a new mirror to replace the light, the LED light strips are expensive and somewhat difficult to replace. You must take apart and remove the mirror from the vehicle using a flat-head screwdriver and a Phillips screwdriver.

Push the side mirror up against the car as far as it can go. Do not break the mirror.

Insert a flat-head screwdriver underneath the mirror and pry out the clip holding the mirror housing in place. This will allow access to the inside of the mirror assembly.

Remove the mirror assembly from the vehicle and place it on a level surface. Use a Phillips screwdriver to remove the two screws holding the old LED light strip in place.

Snap the new LED light strip into the mirror assembly and reattach the two screws. Place the mirror assembly back into the mirror housing, making sure to connect the two center inputs to the four-prong female connector located on the back of the mirror housing.

Reattach the clip to secure the assembly to the housing. Test the lights. If they are not working, you may have connected the mirror improperly. Adjust the mirror if necessary.
